A circle has a radius of 3 miles. Use the work shown below to identify the area in terms of pi and the approximate area of the circle. Use 3.14 for π and round the answer to the nearest tenth. A = πr2 A = π(3 mi)2 A = 3.14(9 mi) The area in terms of pi is Pi mi2. The approximated value for the area is .

Given:

Given that the radius of circle is 3 miles.

We need to determine the area of the circle.

Area of the circle:

The area of the circle can be determined using the formula,

where r is the radius of the circle.

Substituting π = 3.14 and r = 3 in the above formula, we get;

Simplifying, we get;

Multiplying, we have;

Rounding off to the nearest tenth, we get;

Thus, the area of the circle is 28.3 square miles.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
